LeakLens – Privacy-inspecteur

Bekijk wat u deelt met elke website — machtigingen, trackers, cookies, fingerprinting — en neem de controle over uw privacy.

LeakLens is a comprehensive privacy inspector that reveals what data you share with every website you visit — and gives you granular control over each piece. Trackers follow you across the web. Fingerprinting scripts silently identify your browser. Cookies persist long after you leave a site. Security headers go unchecked. LeakLens makes all of this visible — with real-time analysis, actionable scores, and one-click protection tools that work entirely in your browser. ✅ One purpose: help you understand and control the data you share with websites 🧩 Deep analysis: trackers, cookies, fingerprinting, security headers, permissions — all in one view 🔒 Privacy-first: no data collection, no analytics, no external connections --- Key Features (at a glance) * 🔍 Real-Time Privacy Audit — instant security posture score (0–100) and risk grade (A–F) for every website * 🛡️ Tracker Blocking — block trackers with explainable rules in Balanced, Strict, or Custom modes * 🧹 URL & Redirect Cleaner — automatically strip tracking parameters (UTM, gclid, fbclid, and more) * 🔐 Fingerprint Detection — detect Canvas, WebGL, Audio, and WebRTC fingerprinting in real-time * 🌐 WebRTC & Network Leak Shield — prevent IP leaks and block requests to private IP ranges * ⏱️ Temporary Permission Grants — allow geolocation, camera, or mic temporarily with auto-revoke * 🔒 Session Shield — per-tab session isolation with cookie management * 📊 Security Headers Analyzer — analyze HSTS, CSP, Permissions-Policy, and more with actionable recommendations * 📋 Context Menu — quick actions: inspect, shield, block trackers, clear data, open in isolation * 📌 Pin & Drag Overlay — float LeakLens on any page, drag it anywhere * ⚙️ Advanced Settings — per-domain rules, editable tracker lists, import/export configuration * 🌍 21 Languages — full internationalization --- What LeakLens Helps You Do 🔍 Understand Your Privacy Exposure See exactly what's happening on every website you visit. * Instant privacy score (0–100) based on trackers, cookies, fingerprinting, and headers * Risk grade (A–F) at a glance in the toolbar badge * Timeline of all privacy-relevant events per domain * Per-domain breakdown of active trackers, cookies, and fingerprint signals --- 🛡️ Block Trackers with Transparency Stop tracking scripts — and understand exactly which ones and why. * Three protection modes: Balanced, Strict, or Custom * Explainable blocking — see which rule matched and why each tracker was blocked * Domain-level blocking controls for fine-grained management * Bundled tracker lists — no external connections needed --- 🔐 Detect & Mitigate Fingerprinting Know when websites try to fingerprint your browser — and fight back. * Detects Canvas, WebGL, Audio, and WebRTC fingerprinting in real-time * Three modes: Detect (monitor), Prompt (ask), or Mitigate (defend) * Per-signal counters with "last seen" timestamps * Content script injection monitors fingerprint API calls --- 🧹 Clean Tracking Parameters Automatically Remove the invisible tracking data hidden in URLs. * Automatically strips UTM, gclid, fbclid, and 20+ tracking parameters * Editable parameter list — add or remove tracked parameters * Works silently in the background on every navigation --- 🌐 Prevent Network Leaks Stop your real IP and local network from being exposed. * Controls WebRTC IP handling policy to prevent IP leaks * Local Network Request Guard detects and blocks requests to private IP ranges * TLS & Certificate Inspector shows TLS version, cipher suite, issuer, validity (Firefox) --- ⏱️ Control Permissions Temporarily Grant sensitive permissions only for as long as you need them. * Grant geolocation, camera, microphone, or notifications temporarily * Options: Allow once, 10 minutes, 1 hour, or Always * Permissions auto-revoke after the timer expires — no manual cleanup needed --- 📊 Audit Security Headers Understand how well each website protects its visitors. * Analyzes HSTS, CSP, Permissions-Policy, X-Frame-Options, and more * Calculates a Security Posture Score (0–100) * Shows per-header status with actionable recommendations --- Designed for Clarity (Not Feature Bloat) LeakLens packs serious privacy analysis into a clean, focused interface. * ✨ Elegant popup with tabbed navigation and real-time scores * ⚡ Lightweight — minimal performance impact * 🧠 Explainable results — every blocked tracker, every risk flag has a reason * 📌 Draggable, pinnable overlay — stays on screen while you browse * 🔁 Works across SPA navigation without needing reloads * 🌍 Available in 21 languages --- Privacy & Data LeakLens does not: * collect personal data * track your browsing behavior * run analytics or profiling * contact any external servers It works entirely locally in your browser.
